Unity Release 6.10.0

• This release was tested against Unity 2020LTS and 2021LTS
• Tracking contains stable content including Core, Hands and the Interaction Engine.
• Tracking Preview contains experimental/pre-release content.

Headline features of 6.10.0 include:

Added

• (XRHands) Direct Leap XRHands Subsystem
• (UltraleapSettings) Ultraleap Settings ScriptableObject to toggle features
• (InputSystem) A XRHands to Leap InputActions and Meta Aim InputActions converter

Changed

• (Hand Pose) Removed unnecessary Hand Pose scriptable context menu option
• (Multi device aggregation) Added wrist and arm to ConfidenceInterpolation aggregator
• (Preview XRI) Removed XRI content from Preview Package in favour of XRHands+XRI content in Tracking Package. Follow the Ultraleap XR Docs for XRI and XRHands to get started

Fixed

• (Preview) CPU performance issues on PICO when re-connecting tracking device

Known issues

• Use of the LeapCSharp Config class is unavailable with v5.X tracking service
• Repeatedly opening scenes can cause memory use increase
• Currently the Ultraleap Hand Tracking feature for OpenXR requires the New and Legacy input systems to be enabled, to simultaneously use OpenXR and the Ultraleap Unity Plugin's features.
• The OpenXR Leap Provider does not currently support the Confidence hand property (and will return fixed values)
• If using OpenXR when using Unity 2020 and Ultraleap Tracking Plugin via .unitypackage, an error will appear on import relating to HandTrackingFeature. This has been fixed by Unity on Unity 2021
  • A workaround is to right click on \ThirdParty\Ultraleap\Tracking\OpenXR\Runtime\Scripts\HandTrackingFeature.cs and select 'Reimport'
• After using Ultraleap OpenXR in Unity Editor, the tracking mode of device 0 will be set to HMD until the Unity Editor session ends. This can stop the testing of non-XR scenes until the Unity Editor is re-opened
• The OpenXR Leap Provider palm can be in unexpected position when using pre-1.4.3 OpenXR Layer. A workaround is to ensure you use 1.4.3 or newer - installed by the 5.12.0 or newer Tracking Service Installer
• Running both the Ultraleap XRHands Subsystem and another XRHands Subsystem at the same time causes unstable results. Only enable one at a time.

Note

If using the .UnityPackage method to import the Plugin, it is recommended to delete any previous version before importing to avoid import issues.
